Cabin staff of German national carrier Lufthansa have begun their 24 hour strike resulting in the cancelation of 1,200 flights.
The airline has posted information on the situation on its official website in both German and English.
On Tuesday, Lufthansa cabin crews walked out at Berlin, Frankfurt, and Munich airports, which forced the airline to cancel hundreds of flights.
The flight attendant union (UFO) then called a nationwide strike, Spiegel reports.
The UFO is demanding a 5% pay increase for cabin crew members and assurances on jobs, BBC News reports.
This affected the travel plans of some 43,000 passengers. Around 1,500 of these customers slept on temporary beds in airport lounges.
Lufthansa also sent 18,000 text messages to its customers to inform them about travel disruptions and flight cancellations due to the strike, Reuters reports.
The union has argued that Lufthansa's 18,000 cabin crew members have no received a pay increase in three years. The UFO represents about two-thirds of Lufthansa's cabin crew.
Lufthansa spokesman Klaus Walther said the company is prepared to offer only a 3.5% pay raise.
Earlier this week, UFO head Nicoley Baublies called on the airline to begin mediation in order to halt the strike, Reuters reports.
Lufthansa responded that "the offer already made is enough to return to the negotiating table."
The union, which represents, around two-thirds of Lufthansa's 18,000 member cabin crew, is arguing that they have not received a pay raise in three years.
The decision to strike on a Friday will very seriously affect the airline as according to Spiegel, Lufthansa usually serves 170,000 passengers or more on most Fridays.
The strike affects Germany's six main airports including Munich, Frankfurt, and Berlin, BBC News reports.
Lufthansa is the 4th largest airline in the world, Spiegel reports.
